In a thin film forming method in which a mixture gas which includes a monomer gas and an oxidizing reactive gas is plasmatized and a thin film which is formed of an oxide is formed on a surface of a substrate, the mixture gas is plasmatized while a flow amount ratio of the monomer gas with respect to the reactive gas is varied under the condition that the flow amount ratio is included within at least a specific range. In this case, a thin film forming device 10 in which high frequency electricity is supplied from a high frequency power supply section 30 to a plurality of thin film forming chambers is used. By doing this, it is possible to provide a thin film forming method and a thin film forming device in which it is possible to strictly form a thin film which has characteristics such as a gas barrier property without variation in quality and to provide flexibility to the thin film even if the thin film is formed onto a large number of substrates. Also, in a monitoring method for measuring the intensity of the hydrogen alpha rays and the intensity of the oxygen radiation rays which are radiated from the plasma while forming the thin film and comparing each intensity with a standard intensity of each radiation under the condition that the thin film has a desirable surface quality, and for determining whether or not a thin film which has a desirable surface quality is formed, a thin film forming device is provided with: an optical spectrometer 12 which measures the intensity of each radiation, a storage section which stores a standard intensity of each radiation, and a determining section which determines whether or not each measured intensity is in a specific range by comparing each measured intensity with the standard intensity of each radiation. By doing this, it is possible to determine whether or not the produced thin film has a desirable surface quality during the process.

A mold for plastic bottles is designed to have an internal arithmetic average of roughness height of a cavity-forming wall to be less than 0.25 .mu.m. The mold has air passages for decompressing air in the cavity and absorbing the air between the wall and a parison expanded by blowing into it. The mold has air suction passages around the mouth portion of the mold and between the main body and the bottom portion of the mold. The surface of the bottle and the molds have so little air stagnated between the mold and the bottle wall that the resulting bottle results in a high gloss.

A thin film forming method for plasmatizing a mixture gas, the mixture gas being made up of a monomer gas and an oxidizing reactive gas, and for forming a thin film on a surface of a substrate, the thin film being made of an oxide. The method includes forming a first thin film by plasmatizing the mixture gas while varying a supply flow amount ratio of the monomer gas with respect to the reactive gas and forming a final thin film by increasing the supply flow amount ratio of the monomer gas with respect to the reactive gas after the forming of the first film.
摘要:
This invention relates to a compound container which can completely be separated into paper and plastics upon abandonment thereof, whose volume can substantially be reduced upon abandonment, which permits the reduction of the amounts of paper and plastics to be used, which exhibits excellent resistance to falling impact, which has a high oxygen gas barrier properties or water vapor barrier properties. This compound container comprises an inner container of a plastic and an outer container of paper or mainly comprising paper, wherein the inner container is produced by blow-molding or stretch blow-molding a resin composition comprising at least two resins including a barrier resin.
